Root Cause

Attempting to save a figure to a directory that does not exist.

generic

中文

尝试将图形保存到不存在的目录。

Workarounds

  1. 95% success Create the directory before saving 
    import os; os.makedirs('/nonexistent/path', exist_ok=True); plt.savefig('/nonexistent/path/figure.png')
  2. 90% success Use a valid existing directory 
    plt.savefig('./figure.png')

Dead Ends

Common approaches that don't work:

  1. Using a relative path without checking current working directory 70% fail

    If the relative path points to a non-existent directory, the error persists.

  2. Creating the file manually before saving 90% fail

    The directory must exist; creating the file alone does not create parent directories.
